thinkphp自动生成sitemap网站站点地图
首先用的是
米扑科技的开源项目：sitemap-php 自动生成网站地图
使用方式可以去github上看文档 https://github.com/mimvp/mimvp-sitemap-php
function testSitemap() { $sitemap = new \app\extra\Mysitemap("http://mimvp.com"); $sitemap->addItem('/', '1.0', 'daily', 'Today'); $sitemap->addItem('/hr.php', '0.8', 'monthly', time()); $sitemap->addItem('/index.php', '1.0', 'daily', 'Jun 25'); $sitemap->addItem('/about.php', '0.8', 'monthly', '2017-06-26'); $sitemap->addItem('/hr2.php', '1.0', 'daily', time())->addItem('/index2.php', '1.0', 'daily', 'Today')->addItem('/about2.php', '0.8', 'monthly', 'Jun 25'); $sitemap->endSitemap(); }
后台效果是自己做的
核心代码：
首先在extra目录下引入类文件
Mysitemap.php
<?php namespace app\extra; use XMLWriter; /** * Sitemap * * 生成 Google Sitemap files (sitemap.xml) * * @package Sitemap * @author Sandy <sandy@mimvp.com> * @copyright 2009-2017 mimvp.com * @license http://opensource.org/licenses/MIT MIT License * @link http://github.com/mimvp/sitemap-php */ class Mysitemap { private $writer; // XMLWriter对象 private $domain = "http://mimvp.com"; // 网站地图根域名 private $xmlFile = "sitemap"; // 网站地图xml文件（不含后缀.xml） private $xmlFileFolder = ""; // 网站地图xml文件夹 private $currXmlFileFullPath = ""; // 网站地图xml文件当前全路径 private $isSchemaMore= true; // 网站地图是否添加额外的schema private $current_item = 0; // 网站地图item个数（序号） private $current_sitemap = 0; // 网站地图的个数（序号） const SCHEMA_XMLNS = 'http://www.sitemaps.org/schemas/sitemap/0.9'; const SCHEMA_XMLNS_XSI = 'http://www.w3.org/2001/XMLSchema-instance'; const SCHEMA_XSI_SCHEMALOCATION = 'http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd'; const DEFAULT_PRIORITY = 0.5; const SITEMAP_ITEMS = 50000; const SITEMAP_SEPERATOR = '-'; const INDEX_SUFFIX = 'index'; const SITEMAP_EXT = '.xml'; /** * @param string $domain ： 初始化网站地图根域名 */ public function __construct($domain) { $this->setDomain($domain); } /** * 设置网站地图根域名，开头用 http:// or https://, 结尾不要反斜杠/ * @param string $domain ： 网站地图根域名 <br>例如: http://mimvp.com */ public function setDomain($domain) { if(substr($domain, -1) == "/") { $domain = substr($domain, 0, strlen($domain)-1); } $this->domain = $domain; return $this; } /** * 返回网站根域名 */ private function getDomain() { return $this->domain; } /** * 设置网站地图的xml文件名 */ public function setXmlFile($xmlFile) { $base = basename($xmlFile); $dir = dirname($xmlFile); if(!is_dir($dir)) { $res = mkdir(iconv("UTF-8", "GBK", $dir), 0777, true); if($res) { //echo "mkdir $dir success"; } else { //echo "mkdir $dir fail."; } } $this->xmlFile = $xmlFile; return $this; } /** * 返回网站地图的xml文件名 */ private function getXmlFile() { return $this->xmlFile; } public function setIsChemaMore($isSchemaMore) { $this->isSchemaMore = $isSchemaMore; } private function getIsSchemaMore() { return $this->isSchemaMore; } /** * 设置XMLWriter对象 */ private function setWriter(XMLWriter $writer) { $this->writer = $writer; } /** * 返回XMLWriter对象 */ private function getWriter() { return $this->writer; } /** * 返回网站地图的当前item * @return int */ private function getCurrentItem() { return $this->current_item; } /** * 设置网站地图的item个数加1 */ private function incCurrentItem() { $this->current_item = $this->current_item + 1; } /** * 返回当前网站地图（默认50000个item则新建一个网站地图） * @return int */ private function getCurrentSitemap() { return $this->current_sitemap; } /** * 设置网站地图个数加1 */ private function incCurrentSitemap() { $this->current_sitemap = $this->current_sitemap + 1; } private function getXMLFileFullPath() { $xmlfileFullPath = ""; if ($this->getCurrentSitemap()) { $xmlfileFullPath = $this->getXmlFile() . self::SITEMAP_SEPERATOR . $this->getCurrentSitemap() . self::SITEMAP_EXT; // 第n个网站地图xml文件名 + -n + 后缀.xml } else { $xmlfileFullPath = $this->getXmlFile() . self::SITEMAP_EXT; // 第一个网站地图xml文件名 + 后缀.xml } $this->setCurrXmlFileFullPath($xmlfileFullPath); // 保存当前xml文件全路径 return $xmlfileFullPath; } public function getCurrXmlFileFullPath() { return $this->currXmlFileFullPath; } private function setCurrXmlFileFullPath($currXmlFileFullPath) { $this->currXmlFileFullPath = $currXmlFileFullPath; } /** * Prepares sitemap XML document */ private function startSitemap() { $this->setWriter(new XMLWriter()); $this->getWriter()->openURI($this->getXMLFileFullPath()); // 获取xml文件全路径 $this->getWriter()->startDocument('1.0', 'UTF-8'); $this->getWriter()->setIndentString("\t"); $this->getWriter()->setIndent(true); $this->getWriter()->startElement('urlset'); if($this->getIsSchemaMore()) { $this->getWriter()->writeAttribute('xmlns:xsi', self::SCHEMA_XMLNS_XSI); $this->getWriter()->writeAttribute('xsi:schemaLocation', self::SCHEMA_XSI_SCHEMALOCATION); } $this->getWriter()->writeAttribute('xmlns', self::SCHEMA_XMLNS); } /** * 写入item元素，url、loc、priority字段必选，changefreq、lastmod可选 */ public function addItem($loc, $priority = self::DEFAULT_PRIORITY, $changefreq = NULL, $lastmod = NULL) { if (($this->getCurrentItem() % self::SITEMAP_ITEMS) == 0) { if ($this->getWriter() instanceof XMLWriter) { $this->endSitemap(); } $this->startSitemap(); $this->incCurrentSitemap(); } $this->incCurrentItem(); $this->getWriter()->startElement('url'); $this->getWriter()->writeElement('loc', $this->getDomain() . $loc); // 必选 $this->getWriter()->writeElement('priority', $priority); // 必选 if ($changefreq) { $this->getWriter()->writeElement('changefreq', $changefreq); // 可选 } if ($lastmod) { $this->getWriter()->writeElement('lastmod', $this->getLastModifiedDate($lastmod)); // 可选 } $this->getWriter()->endElement(); return $this; } /** * 转义时间格式，返回时间格式为 2016-09-12 */ private function getLastModifiedDate($date=null) { if(null == $date) { $date = time(); } if (ctype_digit($date)) { return date('c', $date); // Y-m-d } else { $date = strtotime($date); return date('c', $date); } } /** * 结束网站xml文档，配合开始xml文档使用 */ public function endSitemap() { if (!$this->getWriter()) { $this->startSitemap(); } $this->getWriter()->endElement(); $this->getWriter()->endDocument(); $this->getWriter()->flush(); } /** * Writes Google sitemap index for generated sitemap files * * @param string $loc Accessible URL path of sitemaps * @param string|int $lastmod The date of last modification of sitemap. Unix timestamp or any English textual datetime description. */ public function createSitemapIndex($loc, $lastmod = 'Today') { $indexwriter = new XMLWriter(); $indexwriter->openURI($this->getXmlFile() . self::SITEMAP_SEPERATOR . self::INDEX_SUFFIX . self::SITEMAP_EXT); $indexwriter->startDocument('1.0', 'UTF-8'); $indexwriter->setIndent(true); $indexwriter->startElement('sitemapindex'); $indexwriter->writeAttribute('xmlns:xsi', self::SCHEMA_XMLNS_XSI); $indexwriter->writeAttribute('xsi:schemaLocation', self::SCHEMA_XSI_SCHEMALOCATION); $indexwriter->writeAttribute('xmlns', self::SCHEMA_XMLNS); for ($index = 0; $index < $this->getCurrentSitemap(); $index++) { $indexwriter->startElement('sitemap'); $indexwriter->writeElement('loc', $loc . $this->getFilename() . ($index ? self::SITEMAP_SEPERATOR . $index : '') . self::SITEMAP_EXT); $indexwriter->writeElement('lastmod', $this->getLastModifiedDate($lastmod)); $indexwriter->endElement(); } $indexwriter->endElement(); $indexwriter->endDocument(); } }
然后控制器里使用
function testSitemap() { $sitemap = new \app\extra\Mysitemap("http://mimvp.com"); $sitemap->addItem('/', '1.0', 'daily', 'Today'); $sitemap->addItem('/hr.php', '0.8', 'monthly', time()); $sitemap->addItem('/index.php', '1.0', 'daily', 'Jun 25'); $sitemap->addItem('/about.php', '0.8', 'monthly', '2017-06-26'); $sitemap->addItem('/hr2.php', '1.0', 'daily', time())->addItem('/index2.php', '1.0', 'daily', 'Today')->addItem('/about2.php', '0.8', 'monthly', 'Jun 25'); $sitemap->endSitemap(); }
我操作的时候遇到个坑，就是thinkphp报错：XMLWriter 没找到
一开始我以为是没有装XMLWriter扩展，phpinfo发现是有的，后来就在类文件Mysitemap.php，头部加上
namespace app\extra; use XMLWriter;
就可以了、
